当你创建一个对象时，你需要用def __init__(self, in_array)初始化它。这里我包含了一个简单的append和show方法。我包含了show方法来演示append的工作。dubbbdan的答案中的代码肯定有其价值，但我建议下面的实现：
def pad_to_match(arr, target_shape, fill_value=0): """Pad array to match target shape along axis 1""" result = np.full((arr.shape[0], target_shape[1]), fill_value) result[:, :arr.shape[1]] = arr return result # Pad arr1 to match width of arr2 arr1_padded = pad_to_m...

self: open3d.core.Tensor:待新增元素的张量。 t: Union[open3d.core.Tensor, numpy.ndarray]:欲新增的元素。可以是张量或者NumPy数组。返回值返回新增元素后的张量。注意事项张量的shape必须与新增元素的shape匹配。 对于新增加的元素,会向张量中添加一维。 如果新增元素是张量,则它必须与待新增元素的张量具有相同...
